Joachim Lange
...is senior engineer for power systems and IEC 61850 at Solvay (Europe)
Received his Diploma in electrical machines & power electronics at Technical University Fredericana Karlsruhe (nowadays KIT), hereafter in 1986, he entered into maintenance and engineering department in Solvay’s Rheinberg site; got 1989 head of department electrical engineering in Kali Chemie AG in Bad Hönningen, then 1991 department manager electrical studies at Solvay Deutschland GmbH (Direktion Technik). Since 1998 Senior Engineer in Solvay S.A. - Direction Centrale Technique - Brussels (Belgium), allocated in Germany since 2014.
Joachim Lange’s key missions were electrical brown field expansion projects for Solvay’s power demanding chemical plants involving calculation studies and protection design up to 220 kV and up to 240 MW, high-current DC systems up to 200kA as well as electrical connection clarification with RSO and TSO on international level (F, D, ES, B, RU, CO, BR, ARG, US).
One mission was migrating a bunch of proprietary dispatching systems in industrial plants into a future oriented platform using database in combination with multi-protocol frontends embedding IEC standardized protocols like IEC 60870-5-10, and since 2004 new IEC 61850 Edition 1 for protection devices. Vendor proprietary protocols and communication buses were erased. Since 2004 Communication always passes by TCP/IP network (IEC 60870-5-101 and - 103 using serial port servers with RS485) suppressing substation controllers and using IEDs as servers.
Since 2016, in European brown field projects, power plants require smart grid controls with TSO protocol communication for reactive power control (Q(U), Q and active power P limitation. For RSO &TSO the CRA settles new requirements for routers, interface RTUs, static VLAN technologies, firewalls, and flexible tap changer control. More about such brown field projects using IEC 61850, examples will be part of the proposed workshop.
